Abstract

The invention discloses a fan blade icing detection method, device and equipment and a computer storage medium. The draught fan blade icing detection method comprises the steps that P images are obtained, the images are obtained by shooting draught fan blades, and P is a positive integer; respectively inputting the P images into a blade detection model, a blurred image detection model and an icing detection model which are obtained through pre-training to obtain P blade detection results, P blurred image detection results and P first icing detection results; and inputting the P blade detection results, the P blurred image detection results and the P first icing detection results into a pre-trained classification model to obtain a second icing detection result. In the embodiment of the invention, the second icing detection result can more reliably reflect whether the fan blade is iced or not, and the accuracy of icing detection of the fan blade is improved.

Description

technical field [0001] The application belongs to the technical field of wind power generation, and in particular relates to a method, device, equipment and computer storage medium for detecting icing of fan blades. Background technique [0002] Wind energy, as a clean and renewable energy, has been increasingly valued by people, and wind power generators (hereinafter referred to as fans) can be used to convert wind energy into electrical energy. When ice is formed on the blades of the wind turbine, it will increase the load and even cause safety accidents such as blade breakage. In the related technology, the icing condition of the fan blades is detected based on the images captured by the fan blades. However, due to the influence of the diversity of the fan environment, the image quality of the fan blades is uneven, which leads to the failure of the fan blade icing detection. Less accurate.
